What Onyx Valve does

Onyx Valve Company is a Cinnaminson, New Jersey-based American manufacturer specializing in flow control hardware for industrial and municipal fluid handling. Founded in 1995 and operating with 11-50 employees, the company designs and builds three core product families: pinch valves (15 series spanning manual, pneumatic, and electric actuation with full-round or pre-pinched ports and single or dual pinch mechanisms), duckbill and slip-in check valves (8 series for backflow prevention at pipe ends or inline), and pressure sensor isolator rings (4 series plus diaphragm seals, a calibrating machine, a syringe kit, and the Smart Box 4 pump controller). All machining of valve castings, parts, and rubber sleeves is performed in-house at the New Jersey facility to machine-tool tolerances, and the company holds a patent on its Module Seal technology — a hermetic membrane plus Stinger Fitting that enables in-situ instrument replacement on isolator rings without breaking the vacuum fill or removing the ring from the process pipe.

The underlying technology addresses flow control and pressure measurement in abrasive, viscous, and corrosive service environments — slurries, chemicals, raw sewage, mining minerals, biogas, and landfill gas — where traditional valves and instruments would clog, corrode, or fail. Pinch valves provide a clog-resistant full-round opening with no packing and compression-molded replaceable rubber sleeves; duckbill check valves operate with no mechanical moving parts; and isolator rings isolate pressure instruments from process media using an ultra-deep vacuum fill that the company positions as industry-leading for accuracy.

Onyx runs a pure direct B2B sales model with no e-commerce, no resellers, and no self-serve channel; every sale is initiated through a "Request A Quote" inquiry. Revenue is generated entirely through hardware sales — pinch valves, check valves, isolator rings, diaphragms, accessories, and the Smart Box 4 controller — with no recurring SaaS or service-contract component disclosed. The customer base is anchored in municipal water and wastewater treatment (Tampa Bay Water, NEORSD Eastern Treatment Plant), with additional exposure to chemical, pulp and paper, mining, agriculture, food, biogas, dry-material conveying, air pollution control, and storm water applications. Notable project wins include 60+ pinch valves at Tampa Bay Water (Clearwater, FL), 75+ pinch valves plus 6 duckbill valves at NEORSD, and 4 duckbill check valves for the Route 73 flood mitigation project in South Jersey. Geographic reach spans the US Northeast, Southeast, and Midwest with no international footprint disclosed.

Core offering

Onyx Valve manufactures and supplies industrial flow control products, primarily pinch valves (manual, pneumatic, and electric), duckbill-style check valves for backflow prevention, and pressure sensor isolator rings. All products are American-made with in-house machining of valve castings and parts, and are sold direct to municipal and industrial customers via a quote-based B2B sales process.

Product overview

Onyx Valve Company is a manufacturer of industrial flow control products, primarily pinch valves, check valves (duckbill type), and pressure sensors. The product portfolio is organized into three core product lines: (1) Check Valves including multiple duckbill valve series (DBS, DBF, DBCP, DBRS, DBMJ, DBMJF, ILCV, WCV) designed for preventing backflow in pipelines; (2) Pinch Valves available in manual (CHR, CHP, DHC, DHA, DHO), pneumatic (DAC, GSS, GSF, GSD, CAR, CAP, DAO), and electric (CER, CEP, DEC) configurations, distinguished by port type (full round vs. pre-pinched), enclosure style (enclosed vs. open-frame), and pinch mechanism (single vs. dual); and (3) Pressure Sensors featuring isolator rings (PSW, PSR, PSS, PSQ) with different pipe connection types, diaphragm seals (Model K), and accessories including calibrating machines, syringe kits, and the Smart Box 4 pump controller. All products are manufactured in America with 20 years of industry experience, serving water treatment, wastewater, mining, chemical, food, and other industrial applications.
